Effects of Climate Variability on Two Commercial Tuna Species Abundance in the Indian Ocean

open access: yesFishes, 2023
Oceanic temperature fluctuations are one of the leading factors affecting marine fish populations. Indian Ocean Dipole (IOD), characterized as the sea surface temperature (SST) anomaly change, is an ocean–atmosphere interactive process causing ...

Factors that determine the quality of bigeye tuna, caught in the western tropical Atlantic Ocean

open access: yesArquivo Brasileiro de Medicina Veterinária e Zootecnia, 2014
Tuna are highly prized in Oriental cuisine, and the bigeye tuna (Thunnus obesus) is of great commercial importance. Quality is assessed by the tuna meat quality, freshness, texture and fat, which can be altered by factors inherent to capture, such as ...

Interannual Variability of Yellowfin Tuna (Thunnus albacares) and Bigeye Tuna (Thunnus obesus) Catches in the Southwestern Tropical Indian Ocean and Its Relationship to Climate Variability

open access: yesFrontiers in Marine Science, 2022
This study investigated the interannual variability of yellowfin tuna (Thunnus albacares) and bigeye tuna (Thunnus obesus) catches in the southwestern tropical Indian Ocean (SWTIO) over 25 years and its relationship to climate variability.

MASS SPECTROMETRIC ANALYSIS FOR THE IDENTIFICATION OF THUNNUS GENUS FOUR SPECIES

open access: yesItalian Journal of Food Safety, 2011
An accurate identification of similar fish species is necessary to prevent illegal substitution and is imposed by labeling regulations in UE countries (1). The genus Thunnus comprises many species of different quality and commercial value. The increasing

The state of knowledge on four families of Syngnathoidei fishes (Teleostei: Syngnathiformes): Aulostomidae, Centriscidae, Fistulariidae and Solenostomidae

open access: yesJournal of Fish Biology, EarlyView.
Abstract Knowledge on the ecology and life‐history traits of coastal marine species is vital to inform their conservation and management, especially as their coastal habitats come under increasing threats. However, such data have never been collated for four of the five families in the suborder Syngnathoidei—the close relatives of the better‐studied ...

Pacific bluefin tuna (Thunnus orientalis) bycatch in the Atlantic Ocean

open access: yesJournal of Fish Biology, EarlyView.
Abstract A large tuna was hooked by a Japanese longline fishery in the high seas near the Republic of Namibia. This fishing ground is mainly utilized for Thunnus albacares, Thunnus obesus and Thunnus alalunga by Japanese tuna longliners. Because the tuna was larger than the common size of these species, the specimen was sampled for genetic species ...

Genetic evidence for inter-oceanic subdivision of bigeye tuna ( Thunnus obesus ) populations

open access: yesMarine Biology, 1998
Bigeye tuna (Thunnus obesus Lowe, 1839) are a commercially important species of tuna found in the Atlantic, Indian, and Pacific oceans. To initiate an analysis of bigeye tuna population-structure, three PCR–RFLP assays were developed based on the published mtDNA control-region sequences of four bigeye tuna.

Morphology and Distribution of Olfactory Receptor Neurons in Southern Bluefin Tuna, Thunnus maccoyii (Teleostei): Implications for Olfactory Hydrodynamics

open access: yesJournal of Morphology, Volume 287, Issue 5, May 2026.
The number and distribution of olfactory receptors over the olfactory lamellar surface of four juvenile southern bluefin tuna were quantified using scanning electron microscopy. The microvillous olfactory receptors (mORN) are concentrated in the rostral region of the lamellar surface, while ciliated olfactory receptors (cORN), which are dominant in ...
